Double-Walled Panel For Building

ABSTRACT

A double-walled panel for building includes a double-walled main body defining an inner space and two opposite open sides, and being internally provided with a plurality of spacing boards to divide the inner space into a plurality of chambers, and each of the chambers having two opposite open ends at the two open sides of the main body; a working liquid stored in the chambers in the main body; and at least two sealing covers for sealing the two open sides of the main body as well as the two open ends of each of the chambers. The double-walled panel may be used as a ceiling panel or a partition panel. The working liquid stored in the chambers not only helps in lowering indoor temperature in normal use conditions, but also helps in putting out fire when the building is on fire.

FIELD OF THE INVENTION

The present invention relates to a panel for use in a building, and moreparticularly to a double-walled panel for building that not only helpsin lowering indoor temperature in normal use conditions, but also helpsin putting out fire when the building is on fire.

BACKGROUND OF THE INVENTION

Generally, a conventional ceiling structure includes at least a set oflightweight steel frames connected to an inside roof of a room, and aplurality of plastic panels or gypsum panels is supported on thelightweight steel frames.

The plastic panels and the gypsum panels supported on the lightweightsteel frames are only decorative panels without the function of loweringindoor temperature. Moreover, the plastic panels and the gypsum panelsare easily burned and damaged in a fire to produce a large amount ofblack smoke and toxic gases, which increase people's difficulty insafely leaving the building on fire to result in increased number ofinjured and dead persons.

SUMMARY OF THE INVENTION

A primary object of the present invention is to provide a double-walledpanel for use as a ceiling panel and/or a partition panel in a building,so that the panel not only helps in lowering indoor temperature innormal use conditions, but also helps in putting out fire when thebuilding is on fire.

To achieve the above and other objects, the double-walled panelaccording to the present invention includes a double-walled main bodydefining an inner space and two opposite open sides, and beinginternally provided with a plurality of spacing boards to divide theinner space into a plurality of chambers, and each of the chambershaving two opposite open ends at the two open sides of the main body; aworking liquid stored in the chambers in the main body; and at least twosealing covers for sealing the two open sides of the main body as wellas the two open ends of each of the chambers. The double-walled panelmay be used as a ceiling panel or a partition panel.

The working liquid stored in the chambers not only helps in loweringindoor temperature in normal use conditions, but also helps in puttingout fire when the building is on fire.

BRIEF DESCRIPTION OF THE DRAWINGS

The structure and the technical means adopted by the present inventionto achieve the above and other objects can be best understood byreferring to the following detailed description of the preferredembodiments and the accompanying drawings, wherein

FIG. 2 is an assembled view of FIG. 1;

FIG. 3 is a sectional view taken along line A-A of FIG. 2;

FIG. 4 shows the installation of the double-walled panels of the presentinvention for use as ceiling panels; and

FIG. 5 is an enlarged sectional view of the circled area “a” of FIG. 4.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIGS. 1 and 2 that are exploded and assembledperspective views, respectively, of a double-walled panel for buildingaccording to a preferred embodiment of the present invention, and toFIG. 3 that is a sectional view taken along line A-A of FIG. 2. Asshown, the double-walled panel of the present invention includes a mainbody 1, a working liquid 2, and at least two sealing covers 3.

The main body 1 is double-walled to define an inner space and twoopposite open sides, and may be made of a plastic material. Thedouble-walled main body 1 is internally provided with a plurality ofspacing boards 11 to divide the inner space into a plurality of chambers12, such that each of the chambers 12 has two opposite open ends 121,122 at the two open sides of the main body 1.

The working liquid 2 is stored in the chambers 12 in the main body 1,and may be water or other suitable liquids.

The sealing covers 3 are connected to the two opposite open sides of themain body 1 to seal the open ends 121, 122 of all the chambers 12. Eachof the sealing covers 3 is provided on one surface facing toward themain body 1 with a plurality of insert portions 31 for separatelyinserting into the open ends 121, 122 of the chambers 12 to seal thesame.

Please refer to FIG. 4 that shows the installation of the double-walledpanels of the present invention for use as ceiling panels in a building,and to FIG. 5 that is an enlarged sectional view of the circled area “a”of FIG. 4. As shown, to use the double-walled panels of the presentinvention as a ceiling panels, simply install the already sealed mainbody 1 of the double-walled panels on a predetermined framework 4, suchas a lightweight ceiling suspension system. Of course, the double-walledpanels of the present invention may also be used as interior partitionpanels.

The working liquid 2 in the sealed chambers 12 of the double-walled mainbody 1 provides the function of lowering indoor temperature when theenvironment in which the double-walled panel is used is in normalconditions. In the event the building using the double-walled panels ison fire, the working liquid 2 in the sealed chambers 12 of the main body1 would be heated and vaporized due to the surrounding high temperature.The vaporized working liquid 2 results in expansion and final breakingof the plastic main body 1, so that the working liquid 2 in the chambers12 of the main body 1 flows out of the damaged main body 1 onto burningthings to help in extinguishing the fire.

With the working liquid 2 stored in the chambers 12, the double-walledpanel for building according to the present invention not only helps inlowering indoor temperature in normal use conditions, but also helps inputting out fire, if the building is on fire unfortunately. Therefore,the present invention effectively overcomes the problems in theconventional plastic and gypsum panels and is very practical for use.

The present invention has been described with a preferred embodimentthereof and it is understood that many changes and modifications in thedescribed embodiment can be carried out without departing from the scopeand the spirit of the invention that is intended to be limited only bythe appended claims.
